Hyper Realistic Sky Resource Pack (1.21.5, 1.20.1) completely overhauls Minecraft’s sky with breathtaking, high-definition visuals created using professional-grade 3D rendering tools. Designed to work with OptiFine, this pack introduces ultra-realistic clouds, auroras, moon phases, and a custom sun texture that elevate your in-game atmosphere. The clouds and auroras are created in Blender using volumetric VDB data and procedural nodes, resulting in dynamic shapes that feel alive in the sky. The moon’s surface is based on real NASA textures, rendered with lighting that reveals its cratered terrain in exceptional detail. The sun, meanwhile, features a hand-painted look crafted in GIMP, offering a smooth contrast to the photorealistic elements. While it’s a large and high-resolution pack, the visual payoff makes it a standout choice for sky customization and immersive gameplay.

Features:
- Custom high-res clouds and auroras built using Blender’s volumetric rendering.
- Moon textures based on NASA satellite data, realistically lit to reveal surface geometry.
- Custom sun design hand-painted in GIMP for a balanced visual tone.
- Seamless integration into Minecraft with OptiFine’s custom sky support.
